It is worth mentioning that, the high-end SSD using MLC flash memory, the amount of written data is more than 2.2PB, and the second Samsung 850 Pro hard drive in the test even wrote 9.1PB of data. Knowing that the official service life is only 150TB, if you write 40GB per day according to this test result, this SSD can theoretically last for 623 years, which is too exaggerated, right?The above is just a theoretical calculation. The German Heise website has done an SSD service life test. The Samsung 750 EVO 250GB cheap TLC SSD can write up to 1.2PB, while the 850 PRO 256GB high-end SSD can reach 9.1PB, enough It proves that the actual service life of SSD is much higher than the official nominal value, and the service life of SSD is super long.Regular brands use solid-state hard drives with regular flash memory particles, so there is no need to worry about the lifespan. It is no problem to basically use up the five-year warranty period.Of course, there are still many regular particles on the market that are said to be used, but in fact they use white chips or even black chips. The service life and speed of different solid state can be said to be completely different, so everyone needs to be cautious when assembling the machine.But sharp-eyed gamers will definitely feel that the Trion 100 has a sense of familiarity. It turns out that this controller is a TLC SSD product created by the parent company Toshiba and the Taiwanese manufacturer Phison.But why not use the well-reviewed Barefoot 3 controller?

Chapter content

Moreover, the technology of solid-state hard drives is also improving: last year, Intel announced for the first time that the Chinese name of the new storage technology of 3DX Point Optance is "Shanteng".But considering that everyone's computer life is only a few years, the life of the solid-state hard drive is actually enough.Provide 3,000 erasing MLC (capacity up to 4TB), 20,000 erasing StrongMLC (capacity halved, write durability and performance upgrade), 10,000 erasing TLC (with high TBW main control, epoch-making industrial-grade TLC product), 40,000 Sub-erasing StrongTLC (capacity reduced to 1/3, write endurance performance upgrade, currently planned to launch in 2020 H1).

Trion 100 comes with a three-year ShieldPlus warranty and an MTBF reliability of 1.5M hours.The author thinks that when buying TLC SSD products, you can choose products with large capacity, such as 960GB or 480GB used in this test, which are quite suitable, because the larger the capacity of SSD, the more durable the product will be, plus the price of TLC products in the future It will definitely be fine-tuned, and it is bound to be sweeter than MLC products, so buying it as a stand-alone game or program installation disc is also a good choice.First of all, the core IC of the PCI-E SSD is Phison PS5012-E12S, which provides the PCIe Gen3x4 NVMe communication protocol. The official data only gives the throughput capacity of 512GB / 1TB. Just looking at the data, it is also in this price range M.2 standard access speed.

The 970 EVO applies Dynamic Thermal Protection technology to automatically monitor and maintain optimal operating temperatures to maximize long-lasting performance.Generally speaking, it is difficult to achieve this TBW within the warranty period, because this number is generally relatively large, far greater than the amount of writing in daily use. The above picture is my own M5P, which has been used for more than 3 years. , the amount of written data is 11214GB, which is almost 11TB, but it is still quite far from its write life, and the durability given by the manufacturer is actually far lower than the actual life of SSD flash memory.Today's solid-state drives usually have a durability indicator in addition to telling you what the warranty period is, and this durability is usually TBW or DWPD. TBW refers to the lifetime write volume of SSD, and DWPD It is the number of times the SSD can be written as a whole per day. The latter is usually used on server-level SSDs because these SSDs have a longer lifespan, while consumer-grade SSDs are basically marked with TBW. In terms of storage performance, TLC flash memory is more economical than SLC and MLC, but the relative number of erasures is a natural danger of TLC flash memory, so manufacturers are launching SSD products using TLC flash memory Therefore, more efforts must be made to optimize the controller and firmware of the SSD, so that the SSD products using TLC can meet the expectations of players.As far as the author's computer experience is concerned, the service life of the hardware needs to be at least 3 years to be considered a pass, and after 4-5 years, it is actually possible to prepare for replacement of new products.After all, as described by the famous Moore's Law, the number of transistors in an integrated circuit will double every 18 months, and the technology is changing with each passing day. The 10-year warranty is so beautiful, and I dare not expect that this SSD will still work 10 years later. Whether it works or not, no one knows that the performance of SSD 10 years later will be several times higher than it is today.

If you download 100G of videos every day and then delete them; then the hard disk usage is often 360000 divided by 100G equals 3600, that is, 3600 divided by 366 equals 9.8 years.If it is just ordinary file writing and erasing, it can be used for 5 years based on 196.7GB per day, and the erasure and writing of 5GB per day is also very rare.Again, based on the JEDEC workload used to specify the TBW, the calculation of the daily write volume of the hard disk allows us to use the TBW specification of the hard disk to estimate the tbwssd (or different years) within the warranty period, the hard disk user capacity per day number of writes per day.Thank you, SSD is the English abbreviation of fixed hard disk. It is different from mechanical hard disk in many ways. The difference is that SSD has the advantages of fast startup, no head, no noise, etc. It is not afraid of collision, vibration and instability like mechanical hard disk. More importantly, SSDs can work at higher temperatures (up to 5 or 6 degrees), while mechanical hard disks can only be driven at a maximum temperature of about XNUMX degrees.But having said that, the high speed and high performance of SSD disks also come at a price, and the lifespan is shorter than that of mechanical hard disks, but from the perspective of work efficiency, it is still possible (just like the business term "small profits but quick turnover"), and using XNUMX ~XNUMX years, well kept, should be fine.

Samsung Management Magician helps you keep drivers up-to-date, monitor drive health and speed through a simple and straightforward interface, further enhance hard drive performance, and make SSD management easier and more effective. The 970 EVO M.2 specification can carry up to 2TB capacity, greatly expanding storage capacity and saving space for other components. DWPD (number of writes per day to the entire disk) DWPD is the abbreviation of Drive Writes Per Day, which means the number of times that the solid state drive SSD can be written to the entire disk every day.Most solid-state drives are damaged because of failure of the main components, but short-circuit failure of the power supply components due to some problems such as operation or humidity. Hang up first.Solid-state drives cannot accurately calculate the lifespan, so choosing high-quality brand products and backing up data in time to prevent data loss are the most important.

There are usually two indicators in the industry to measure the lifespan of SSDs, one is DWPD (Drive Writes Per Day) and the other is TBW (Total Bytes Written). These two data indicators will be written in the product specification. TBW refers to the total amount of written data that the SSD can withstand during the design life, and DWPD refers to how many times a day the SSD is written-erase-written to the entire disk, and how many years to guarantee the life of the SSD.The solid-state and M.2 interfaces of the SATA interface are commonly used in solid-state drives, which are composed of main control, cache, and flash memory particles.There are four kinds of flash memory particles from high-end to low-end, SLC\MLC\TLC\QLC, the higher the high-end flash memory particles, the higher the write life.Theoretically, the lifespan of solid-state hard drives is shorter than that of mechanical hard drives, but SSDs are more shock-resistant, so the actual service life is not necessarily worse than that of HDDs.

These two documents define the durability requirements, test environment and test methods for enterprise-class and consumer-class SSDs.In response to the actual usage of industrial control customers, Minbo uses JESD-219A user-level workloads to calculate WAF and TBW.Among them, different writing ratios are defined according to different writing data sizes, so as to simulate the WAF caused by practical applications, and then calculate the durability of SSD.Therefore, when choosing SSD products, you should first understand your computer usage habits, how much capacity SSD you need, and refer to the TBW value provided by the manufacturer, as well as MTBF (mean time between failures) and product warranty years to measure which SSD is the most suitable. suit myself.No, you can do a simple calculation. Now the erasing times of solid-state hard drives are generally about 3000 times; based on the calculation of the colorful SL GB solid-state hard drive I am using now, under the condition of SSD balanced read and write, the solid-state hard drive The total erasable data is 120G multiplied by 3000 times, equal to 360000GB.

The specification is clearly marked on the back, which literally shows that the storage medium is NAND TLC, but that is just a technical specification, and it can be observed whether the performance is good or bad.But the most eye-catching point is the words Made in Taiwan.A German website called Heise online did a very interesting SSD life test before. They bought 6 representative SSDs (12 in total, 2 for each model), including Crucial tbwssd BX 200, OCZ TR150, Samsung 750 Evo, Samsung 850 Pro, SanDisk Extreme Pro, SanDisk Ultra II.Read main control information, life value and health status from Minbo mSMART monitoring software, issue warnings when high risks are present, carry out preventive maintenance management, and improve operational efficiency.Common manufacturers on the market that can independently produce memory chips include: Intel, Samsung, Micron (India), Hynix, Toshiba, SanDisk, and Yangtze River Storage (2020).Manufacturers that cannot independently produce memory chips, but use the above manufacturers to produce qualified chips include: Lite, Plextor, etc. It is recommended to choose a manufacturer that can independently produce memory chips when purchasing.

SLC refers to storing 1-bit data in each storage unit (Cell), while MLC stores 2 bits, and so on, TLC stores 3-bit data.It can be said that a 3C product can promise a 10-year warranty, which can be said to be a very bold act. The product is estimated to be 10 years from the time it is sold, and the planning of product stocking and maintenance materials for these 10 years makes people think about it. Ma, not to mention the SSD 10 years later is still the SSD we know now?But judging from the strategies of SanDisk and Samsung, many players still believe in the 10-year promise. The OSWindows 10 Professional Edition x64 test environment is the same as the previous test desktop. This time the main slot is the second channel M.550_2 provided by ASUS ROG STRIX tbwssd B1-I GAMING. The interface speed is the same as the main character’s PCI- E 3.0 x4 is consistent, and there is a different space from the C slot operating system disk, theoretically speaking, both can meet the actual test environment. tbwssd The warranty period of most brands will be about 3 years, so there is basically no problem, if it is used normally.

The test results of the solid-state drive life are different with different tools, so the value is for reference only and may not be completely accurate.If a variety of hard disk detection tools show that your SSD life is almost exhausted, you need to pay attention at this time. The SSD may really be broken. Please back up important data to other hard disks or U disks in time to avoid data damage due to SSD damage. lost.Software can be used to query the detection information of the solid state. For example, the Toshiba solid state drive used by the editor has a good health of 100%, a temperature of 37°C, and a total of 332/355GB of read and write. As of today, it has been powered on 645 times. The time has reached 3103 hours, where you can view the actual power-on time of the hard disk and the remaining life of the SSD.

For our daily end customers using SSD, generally there will not be a large amount of writing. If the protection is good, it will not be a problem to use it for more than 5 years. TBW and WAF vary depending on usage behavior, and the difference in workload conditions will greatly affect this value.The TBW and WAF calculated by Minbo using JESD-219A user-level workloads do not represent the actual values ​​used by users.This SSD Endurance test means that users can refer to relevant values ​​to determine whether an SSD is suitable for a specific application.The master controller of the solid-state hard disk is responsible for the management of all data on the hard disk. The better master controllers include: Continental, Samsung, and Intel; and Toshiba, Huirong, and Phison that do well.The SLC cache simulates SLC particles to work, so when transferring large files, there will be obvious speed drops.

Take the latest M9Pe released by Plextor as an example. The TBW of the 512GB version is 320, which means that the SSD can write 320TB of data in its lifetime. If DWPD is used as an indicator, multiply the capacity of the SSD by 365 and multiply by the warranty number of years, this will give its TBW.Special statement: The above content (including pictures or videos if any) was uploaded and released by users of the self-media platform "NetEase". This platform only provides information storage services. The TPCIE501 label sticker clearly marks the interface specification, adopts PCIE Gen 3× M Key, and communication protocol NVME 1.3.Although it is not the current flagship, it can be regarded as the mainstream specification, and the C/P value of self-installed machines is the first choice.The contents of the box are only one TPCIE501, which saves even a manual or a warranty card.

Taking the 250GB Samsung 970EVO as an example, the warranty policy is 5 years or 150TBW, and 5 years is 260 weeks. On average, 577GB of writing needs to be completed every week, and an average of 82GB is written every day, which is equivalent to rewriting the hard disk data every three days. Replace it.But the durability is very terrible. It supports 30 full-disk writes per day, and 12.3PB of data can be written for a lifetime, which is more than 21 times that of MLC flash memory. The time is 100 million hours.In the actual test of Heise, the Micron Crucials BX200 has written almost 187TB and 280TB of data, which is at least twice as much as the official promotion. Even Samsung 2 Evo, a cheap TLC flash memory hard drive, also writes 750PB data volume.According to the above information, we know that the warranty period of SSD is generally 1.2 to 3 years.

When choosing a hard drive when assembling a computer, you will find that there are mechanical hard drives and solid-state hard drives on the market, but the working principles of the two hard drives are quite different.The lifespan of a mechanical hard disk is determined by the mechanical structure, and the lifespan of a solid-state disk is generally determined by the lifespan of flash memory particles. tbwssd solid-state hard disk stores data through the characteristics of flash memory NAND Flash. It has evolved from the early SLC era to the current MLC dominance, and the successor TLC is also preparing to shine.

The reason is that Barefoot 3 does not support TLC flash memory, and the next-generation new controller "JetExpress" has not yet been further listed. In view of this, the controller of the parent company Toshiba was adopted and launched. Brand new Trion 100 SSD.If there is a bad, there is a good. Although the durability and performance of TLC will inevitably be questioned, the price per unit of storage will be sweeter. It can be seen that when TLC SSD products are popularized, the price of solid-state hard drives can be made more affordable and the capacity will be higher. big. tbwssd Samsung adopts advanced nickel-plated controller and heatsink in 970 EVO, which has the most excellent heat dissipation performance.
